Abstract

"PROCESSO E SISTEMA DE COMUNICAçõES" Uma mensagem a ser comunicada sobre um enlace de comunicações inseguro (16) é fragmentada (26) em uma pluralidade de pacotes (cada um, talvez de comprimento variável). Os pacotes são então transmitidos individualmente (20) sobre o enlace de comunicações inseguro com um intervalo de tempo (retardo) inter-pacote variável selecionado (talvez, aleatória ou pseudo aleatoriamente). Os pacotes recebidos são, então, remontados (36) para regenerar a mensagem original. Para prover maior segurança contra espionagem, os pacotes não são apenas transmitidos de uma maneira não sincronizada no tempo (28) com o retardo de tempo inter-pacote, mas também são encaminhados (32) sobre diferentes vias de transmissão (34) suportadas pelo enlace de comunicações ou desordenados (30) de uma maneira aleatória ou pseudo aleatória antes da transmissão.
